In science, Year 7 are investigating fossil fuels and learning about oil and natural gas production which have developed from the remains of plants and animals living millions of years ago. We simulated gas production in the lab. Instead of breaking down dead creatures though, we broke down some Alka seltzer tablets with water. Not quite the same, I know, but the gas bubbled up to the surface in the same way, enough to inflate a balloon. Here we are making our gas!
